* fix(ui): allow mouse interaction with LightTooltip interactive content (#1120)
- Remove pointer-events-none from tooltip content so mouse can enter it
- Add tooltipRef to detect hover state on the tooltip itself
- Replace immediate close with scheduleClose (100ms delay) on mouse leave
- Add onPointerDown handler that skips close for clicks inside tooltip
- Extend isTriggerActive() to check tooltip hover alongside trigger hover
Fixes#1120
* fix(ui): prevent click handler from firing on macOS Ctrl+click (#1188)
macOS: Ctrl+click fires both click and contextmenu events.
Elements with both @click and @contextmenu would trigger unwanted
navigation (ObjectBrowser table row, SqlLibraryPanel folder/file,
QueryHistory entry) alongside the context menu.
Fix: add a capture-phase click listener that stops propagation
when ctrlKey is true. This prevents the click from reaching Vue
handlers while the separate contextmenu event is unaffected.
- Add explain_query tool with structured EXPLAIN result, gated on supports_explain_plan()
- Add supports_sql_query() to gate execute_query/get_sample_data for non-SQL DBs (Redis, ES, MongoDB, etc.)
- Split agent loop tool dispatch: execute_query runs sequentially, all others run in parallel via join_all
- Wire explain_query result button to ExplainPlanViewer in AiAssistant + App.vue
- Fix O(n²) agentSteps rebuild: incremental O(1) push per event during streaming
- finally block falls back to full rebuild only when streaming push did not occur
